Fig. 156. The larder-beetle, Dermes- tes lardariiis.—a, la'rva ; b, a single hair from larva ; c, adult beetle. These belong to the family Dermcstidce, which contains such nuisances as the 'larder-beetles,' 'carpet-beetles,' and 'mu- seum-beetles.' The elytra, which cover the abdomen completely, are black or gray, usually ornamented with white or colored scales, which sometimes form quite pretty markings. The 'larder-beetle,' or 'bacon- beetle,' Dermcstes lardarms, is rather more than one-fourth of an inch long, and easily recognizable by having the anterior half of the wing-covers pale brown or yellowish, its livery else being of a sombre black or dark gray. The larva is nearly half an inch in length, rather narrow yet plump, and clothed with rather dense, long, brown hairs. It feeds on stored provisions of all kinds, on hides, skins, or other similar substances, and is occa- sionally quite troublesome in smoke-houses. Cleanliness, plenty of air, tight receptacles, and close-meshed wire netting on the covers or doors of Fig. 157. pantries and boxes are the best prevent ives, supplemented by destruction of the beetles and larvae where^'er noticed. Good results are often obtained by leaving a tempting bit in an exposed position, which will act as a trap, attract- ing beetles and larvae where they can be easily found and destroyed. Several other species, similar in size but differently marked, have similar habits, and among them the 'leather-beetle,' D. znilpiiius, has been responsible
